The Labour leader's office allegedly produced a list ranking the loyalty of MPs from "core" to "hostile". Some anti-Corbyn MPs tell BuzzFeed News they're gutted they aren't considered sufficiently hostile.

The list, which was leaked to The Times, has been the talk of Labour MPs since it was published on Wednesday morning. It attempts to rank almost all the 230 Labour MPs on a five-point scale of "core", "core group plus", "neutral but not hostile", "core group negative", and "hostile".

The MP, who has just returned to parliamentary duties, said all his colleagues were talking about the list in the House of Commons. This had prompted a "huge amount of banter in the tea room" between Labour MPs who wanted to know why some of them had been given overly optimistic loyalty ratings by the leadership team.

He joked it had taken serious illness for him to miss out on being classed as "hostile".

"My assumption as to why I'm in neutral is I went into hospital for two months and my brother had my phone so I couldn't tweet," he said. "I was incommunicado. For five weeks I was in intensive care, three weeks I was in an induced coma."

"It's a very amateurish production, it's got errors and spelling mistakes," he said. "It shows the incompetence of whoever's put it out. Most members of the PLP are treating it as a great big joke."

However, he said his recovery from illness meant he would take his time before trying to be upgraded to the hostile group: "I'm not going to go out of my way to make up for it. I've got to take things steady!"

Meanwhile, other Labour MPs in the "core group negative" section said they were fighting to join the "hostile" category.

One MP, who asked not to be named, said they were considering asking "for an immediate upgrade to hostile".

"My constituents will be cross that I'm not in the hostile group!" they added.

Meanwhile, another anti-Corbyn Labour MP who was baffled to see themselves ranked as "core group negative" but used a BuzzFeed quiz to decide that they really should be in the "hostile" group.
